Abstract:
The purpose of this study was to evaluate the effectiveness and efficiency of a chest radiograph-based detection algorithm for aortic injury and to determine if a previously developed clinical prediction rule would improve imaging efficiency. A 3-year single institution retrospective case-control study with 25 cases of aortic injury and 181 controls was conducted. The detection algorithm correctly identified 96% of all cases of aortic injury, and a definitive diagnosis was established within 6h for 80% of the patients. However, its efficiency was marginal, with only one in 400 chest X-rays leading to a positive diagnosis. The previously developed clinical prediction rule was not able to stratify patients into a clinically useful range of injury probability, and thus the prediction rule cannot be used to improve the efficiency of the existing detection algorithm.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
